Further compression of the already column buckled large-aspect-ratio SWCNTs results in a shell buckling. This shell buckling mode is distinct from that of small-aspect-ratio SWCNTs in that it originates from the column buckling induced bending deformation. The transition strain from column buckling to shell buckling of large-aspect-ratio SWCNTs is predicted using an analytical expression.

The underlying mechanism is discussed by analyzing the variation of C-C bond lengths GSK1904529A order and angles. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3569616]“
“Pressure-assisted thermal processing (PATP) is an advanced thermal process involving application of elevated pressures above 600 MPa on a preheated food for a holding time of 3 to 5 min, causing the volumetric temperature of food to increase above 100 degrees C, to inactivate bacterial spores and enzymes. This study evaluated the influence of PATP on two state-of-the-art multilayer EVOH films. Flexible pouches

containing water as the food simulant were made from the two films and processed at 680 MPa for 3 min at 105 degrees C and 680 MPa for 5 min at 100 degrees C. Each film was investigated for its oxygen transmission rates (OTRs), melting temperature (T(m)), enthalpy of melting high throughput screening (Delta H), and overall crystallinity before (control) and after processing. Staurosporine supplier The changes in OTRs and total Delta H of the two films were also analyzed during a storage period of 240 days in ambient conditions after processing. Results showed a significant (P < 0.05) increase in the OTRs of the two films after PATP. However, PATP did not cause a significant (P > 0.05) change in the T(m) and Delta H of the two films. The overall crystallinity of film A decreased, but improved slightly for film B after PATP. A recovery

in the OTRs of the two films occurred during storage. The films also showed changes in the total Delta H measured during the storage period, which was used to explain the changes in the oxygen barrier properties. The OTR of both films remained below 2 cc/m(2) day, which is required in packaging applications for shelf-stable foods with a 1-year shelf life. This work demonstrates the advantages of using multilayer films containing EVOH as the barrier layer in PATP applications to produce shelf-stable foods. This work also highlights the advantage of, DSC analysis for studying the physical ageing of polymers during storage. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 122: 1538-1545, 2011″
“Primary ovarian insufficiency (POI) is a heterogeneous, multifactorial disorder. Though genetic anomalies, infections, autoimmune disorder and hormonal imbalance are few of the causes of POI, in the majority of patients (50-60%) no etiology has been identified.

Compared with controls, migraineurs had increased relative theta power in all cortical regions and increased delta activity in the painful fronto-central region. Absolute power and asymmetry were similar among groups. In age-adjusted analyses, headache intensity correlated with increased delta activity. In this

blinded controlled study, we found globally increased relative theta activity in migraineurs. A slight interictal brain dysfunction is probably present between attacks.”

“Severe combined immunodeficiency includes a group of diseases characterized by different inherited immunological defects. A 4-month-old girl diagnosed with Omenn syndrome, a subtype of severe combined immunodeficiency presenting with generalized erythroderma, was referred to our hospital for an allogeneic stem cell transplantation. Days before transplantation, she developed hyperpigmented macules that increased in number in the following months. As the erythroderma resolved after transplantation, diffuse hypopigmentation was simultaneously noted together with the expansion of hyperpigmented

lesions. Cutaneous biopsy samples were taken at different moments, showing features of Omenn syndrome at first, and 2 months later changes consistent with hypopigmentation and repigmentation were observed.

“The shape and structural evolution of Co nanoparticles embedded in SiO2 and subjected to swift heavy-ion irradiation have been investigated over a wide energy and fluence range. Sapitinib molecular weight Modifications of the nanoparticle size and shape were characterized with transmission

electron microscopy and small-angle x-ray scattering. Nanoparticles below a threshold diameter remained spherical in shape and progressively decreased in size under irradiation due to dissolution. Nanoparticles above the threshold diameter transformed into nanorods with their major dimension parallel to the incident ion direction. Modifications of the atomic-scale structure of the Co nanoparticles were identified with x-ray absorption spectroscopy. Analysis of the x-ray absorption near-edge spectra showed that prior to irradiation all Co atoms were in a metallic state, while after irradiation Co atoms were in both oxidized and metallic environments, the former consistent with dissolution. The evolution of the nanoparticle short-range order was determined from extended x-ray absorption fine structure spectroscopy. Structural changes in the Co nanoparticles as a function

of ion fluence included an increase in disorder and asymmetric deviation from CAL 101 a Gaussian interatomic distance distribution coupled with a decrease in bondlength. Such changes resulted from the irradiation-induced decrease in nanoparticle size and subsequent dissolution. (C) 2011 American Institute of Physics. [doi:10.1063/1.3587171]“
“Objective.

The shape of the face can be estimated before the surgery by using 3-dimensional computer programs that provide tools to guide skill modifications. The aim of this study was to present the dynamic volume spline method to predict facial soft tissue changes after the modification of the skull associated with orthognathic surgery.

Study design. Soft tissue volume is modeled by a dynamic volume spline that includes the elastic behavior of the actual tissue. The model is a hybrid of spring-mass model and finite element model, and combines their advantageous properties. It provides fast and realistic soft tissue VX-680 simulations. Postsurgical shape of the patient’s face is estimated by reshaping the skull and letting the soft tissue model relax over the new boundary conditions formed by the new skull shape. Postsurgical estimations were compared with the conventional method’s estimations, where the soft tissue is not modeled biomechanically. Also, postsurgical estimations were compared with the actual postsurgical data for 6 orthognathic surgery patients.

Results. The mean of the error between the estimated shapes and the actual postsurgical shapes was similar to 1.8 mm when the whole face was considered.

Conclusion.

It was proposed that exfoliated and intercalated morphology were obtained at low and high-nanobentonite contents, respectively. DMTA indicated that mechanical properties of the dried gel were improved with raising the clay content. In the water-swollen state, storage modulus

“Objective: To compare outcomes of treating complicated skin and skin structure infections (cSSSI) caused by methicillin-resistant Staphylococcus aureus (MRSA) with linezolid versus vancomycin in diabetic and non-diabetic patients.

Methods: We pooled data from three prospective clinical CAL-101 trials in which 1056 patients were randomized to receive either linezolid (intravenous (IV) or oral) or vancomycin (IV) every 12 h, for 7-28 days.

Results: Diabetic (n = 349) and non-diabetic patients (n = 707) had comparable demographics and comorbidities. Clinical success rates were lower in diabetic than in non-diabetic patients (72.3% and 85.8%, respectively). Overall, non-diabetic patients had a shorter adjusted mean length of stay (LOS) compared with diabetic patients (8.2 and 10.7 days, respectively; p <

0.0001). Among diabetic patients, rates were comparable with linezolid and vancomycin treatment for clinical success (74% and 71%, respectively) and microbiological success (60% and 54%, respectively). Among non-diabetic patients, clinical and microbiological success rates were higher in linezolid-than in vancomycin-treated patients (90% and 81%, respectively, and 78% and 65%, respectively). Rates of drug-related adverse events were comparable in diabetic and non-diabetic patients and with linezolid and vancomycin treatment. Adjusted mean LOS was shorter with linezolid than with vancomycin treatment in diabetic patients (9.5 and 11.7 days, respectively; p =

0.03) and non-diabetic patients (7.6 and VX-680 cell line 8.9 days, respectively; p = 0.02).

Conclusions: Clinical success rates were lower in diabetic than non-diabetic patients with cSSSI caused by MRSA. Comparing linezolid and vancomycin, clinical and microbiological success rates were comparable in diabetic patients, but were better for linezolid than for vancomycin in non-diabetic patients.

“The frequency and temperature dependence of the dielectric constant and the ac electrical conductivity in (NH4)(3)FeF6 was investigated. The temperature dependence of the

dielectric constant reveals the phase transition from tetragonal to cubic phase at 270 K. At temperatures below 225 K, the ac conductivity and dielectric constant follow the universal dielectric response (UDR), being typical for hopping or tunneling of localized Daporinad charge carriers. A detailed analysis of the temperature dependence of the UDR parameter s in terms of the theoretical model for tunneling of small polarons revealed that below 225 K this mechanism governs the charge transport in this fluoride system.

“This paper proposes a new method to identify communities in generally weighted complex networks and apply it to phylogenetic analysis. In this case, weights correspond to the similarity indexes among protein sequences, which can be used for network construction so that the network structure can be analyzed to recover

phylogenetically useful information from its properties. The analyses discussed here are mainly based on the modular character of protein similarity networks, explored through the Newman-Girvan algorithm, with the help of the neighborhood matrix (M) over cap. The most relevant networks are found when the network topology AL3818 solubility dmso changes abruptly revealing distinct modules related to the sets of organisms to which the proteins belong. Sound biological information can be retrieved by the computational routines used in the network approach, without using biological assumptions other than those incorporated by BLAST. Usually, all the main bacterial phyla and, in some cases, also some bacterial classes corresponded totally (100%) or to a great extent (>70%) to the modules. We checked for internal consistency in the obtained results, and we scored close to 84% of matches for community pertinence when comparisons between the results were performed.

In addition, increasing Bcl 2 inhibitor evidence supports the idea that amyloid cytotoxicity in most cases is initiated by oligomer recruitment at the cell membrane with loss of membrane integrity, Ca(2+) ingress into the cell, oxidative stress and apoptosis. In such a scenario, increased membrane cholesterol seems to be protective by disfavouring aggregate binding to the membrane. Recent findings also indicate that a reduction of cellular cholesterol favours co-localization of BACE1 and APP in non-raft membrane domains and hinders generation of plasmin, an A beta-degrading enzyme. Finally, recent researches on Seladin-1, involved in cholesterol biosynthesis, show

that modulation of membrane cholesterol affects A beta generation and cell resistance against A beta oligomer toxicity. These data confirm previous findings indicating a reduction of the cholesterol/phospholipid ratio in aged and AD brains.

The aim of this review is to critically discuss some of the main results reported in the recent years in this field supporting a role of cholesterol either as a susceptibility factor or as a protective agent in AD.”

“While anesthetics

are indispensable clinical tools generally safe and effective, in some situations there is grown concern about selective neurotoxicity of these agents; the clinical significance is unclear as of yet. The mechanisms for inhalational anesthetics mediated cell damage are still not clear, although a role for calcium dysregulation has been suggested. For example, the inhaled anesthetic isoflurane decreases endoplasmic reticulum (ER) calcium concentration and increases that in the cytosol and mitochondria. Inhibition of ER calcium release, via either IP(3) or ryanodine receptors, significantly inhibited isoflurane neurotoxicity. Neurons made vulnerable to calcium dysregulation by overexpression of mutated presenilin-1 (PS1) or huntingtin (Q-111) proteins showed enhanced apoptosis upon isoflurane exposure. Sevoflurane and desflurane were less potent than isoflurane in altering intracellular calcium, and produced less apoptosis.

Information exchange and relationship were also integral to decision-making, managing uncertainty, responding to emotions, and self-management. Clinicians who were responsive to patients’ needs beyond the immediate medical encounter were valued.

We present a patient where double intra-atrial connections were capable of different degrees of stimulus propagation from the recipient remnant atrium to the donor atrial compartment. After the ablation of both intra-atrial connections, we also ablated the index arrhythmia in the recipient remnant atrium. This case presentation draws attention to the possibility of the presence SB525334 cell line of multiple intra-atrial connections.

“Purpose: To determine whether a Bayesian network trained on a large database of patient demographic risk factors and radiologist-observed findings from consecutive clinical mammography examinations can exceed radiologist performance in the classification of mammographic

findings as benign or malignant.

Materials and Methods: The institutional review board exempted this HIPAA-compliant retrospective study from requiring informed consent. Structured reports from 48 744 consecutive pooled screening and diagnostic mammography examinations in 18 269 patients from April 5, 1999 to February 9, 2004 were collected. Mammographic findings β-Nicotinamide mouse were matched with a state cancer registry, which served as the reference standard. By using 10-fold cross validation, the Bayesian network was tested and trained to estimate breast cancer risk by using demographic risk factors (age, family and personal history of breast cancer, and use of hormone replacement therapy) and mammographic findings recorded in the Breast Imaging Reporting and Data System lexicon. The performance of radiologists compared with the Bayesian network was evaluated by using area under the receiver operating characteristic curve (AUC), sensitivity, and specificity.

T memory subsets were analyzed by using four-color immunofluorescence staining and flowcytometry. IP-10 and TARC were determined by ELISA. High risk FDRs showed higher levels of CXCR3(+) and lower level of CCR4(+) T memory cells compared to low risk FDRs (64.98 +/- 5.19 versus 42.13 +/- 11.11; 29.46 +/- 2.83 versus 41.90 +/- 8.58%, resp., P < 0.001). Simultaneously, both IP-10 and TARC levels were increased in high risk versus low risk FDRs (160.12 +/- 73.40 versus 105.39 +/- 71.30; 438.83 +/- 120.62 versus 312.04 +/- 151.14 pg/ mL, P < 0.05). Binary logistic regression analysis identified the level of CXCR3(+) T memory cells

as predictors for high risk FDRs, together with high levels of IP-10. The results imply that, in FDRs, the risk for T1D might be strongly

influenced by enhanced activity of Th1 and diminished activity of Th2 autoimmune response.”
“Atomic BGJ398 research buy clocks that fly on global-navigation satellites such as global positioning system (GPS) and Galileo employ light from low-temperature, inductively coupled plasmas (ICPs) for atomic signal generation and detection (i.e., alkali/noble-gas rf-discharge lamps). In this application, the performance of the atomic clock selleck and the capabilities of the navigation system depend sensitively on the stability of the ICP’s optical emission. In order to better understand the mechanisms that might lead to instability in these rf-discharge lamps, and hence the satellite atomic clocks, we studied the optical emission from a Rb/Xe ICP as a function of the rf power driving the plasma. Surprisingly, we found that the electron density in the plasma was essentially independent Small molecule library order of increases in rf power above its nominal value (i.e., “”rf-power gain”") and that the electron temperature was only

a slowly varying function of rf-power gain. The primary effect of rf power was to increase the temperature of the neutrals in the plasma, which was manifested by an increase in Rb vapor density. Interestingly, we also found evidence for electron temperature fluctuations (i.e., fluctuations in the plasma’s high-energy electron content). The variance of these fluctuations scaled inversely with the plasma’s mean electron temperature and was consistent with a simple model that assumed that the total electron density in the discharge was independent of rf power. Taken as a whole, our results indicate that the electrons in alkali/noble-gas ICPs are little affected by slight changes in rf power and that the primary effect of such changes is to heat the plasma’s neutral species.”

“LOV KELCH PROTEIN2 (LKP2), ZEITLUPE (ZTL)/LOV KELCH PROTEIN1 (LKP1) and FLAVIN-BINDING KELCH REPEAT F-BOX1 (FKF1) constitute a family of Arabidopsis F-box proteins that regulate the circadian clock.

Over-expression of LKP2 or ZTL causes arrhythmicity of multiple clock outputs under constant light and in constant darkness. Here, we show the significance of LKP2 and ZTL in the photoperiodic control of flowering time in Arabidopsis. In plants over-expressing LKP2, CO and FT expression was down-regulated under long-day conditions. LKP2 and ZTL physically interacted with FKF1, which was recruited from the nucleus into cytosolic speckles. LKP2 and ZTL inhibited the interaction of FKF1 with CYCLING DOF FACTOR 1, a ubiquitination substrate for FKF1 that is localized in the nucleus. The Kelch repeat regions of LKP2 and ZTL were sufficient for their physical interaction with FKF1 and translocation of FKF1 to the cytoplasm. Overexpression of LKP2 Kelch repeats induced late flowering under long-day conditions.

Methods: A 2-stage scoping review to identify potential outcome areas which were subsequently assessed for their sensitivity to nursing was carried out. Data sources included the Cochrane Library, Medline, Embase, the British Nursing Index, Google and Google scholar.

Results: We identified a broad range of outcomes potentially sensitive to nursing. Individual trials support many nursing interventions find more but we found relatively

little clear evidence of effect on outcomes derived from systematic reviews and no evidence associating characteristics of nursing services with outcomes.

Conclusion: The purpose of identifying a set of outcomes as specifically nurse-sensitive for quality measurement is to give clear responsibility and create an expectation of strong clinical leadership click here by nurses in terms of monitoring and acting on results.
